CENTRIFUG'AL SEPARATOR.

The invention relates to certain improveinonts in centrifugal separatoreot tlie general type disclosed lin my prior patent lilo. 1,119,176,`dated December 1,1914, and has `for its object `to provide the rotorwitli a `iigratlually inclined interior Surface l3etween tlie side Walleand the bottoni, wliieli will prevent tlie packing' oit the :soliil orgritty material between the annular ruido plate and the wall oit tlierotor, and also to construct the perforated screen or itoranii` natetlxSupport :tor tlie annular guide plate of teleeoopingi sections toperinit tlie vertical adjustment olf the annular plate anrl tliereliyvary tlie spaoe Separating tlie periphery oi? the latter troni tlie wallolf the rotor, in, aeeorrlaneo with tlie character of tlio materiallieingg; separated, liquore carryingl a large portion of gritty materialreouirira'i4 a larger opening; or Space between tlio eclg'o oil tli`n'uirle plate and tlie adjacent wall ot tlie bowl or rotor than wouldliquors rifarrying eliniiy, colloidal or 'lloeoulent solid material.

great as to necessitate stopping-the operation and cleaning the bowl.`As hereinbe fore stated, the annular space between the peripheral edgeof the guide plate Vl() and the adjacent inclined or curved surface G ofthe bowl is regulated in accordance with the character of the Solidmaterial carried by the liquor and this regulation is effected byadjusting the perforated plates or screens 1l and 11y relatively to eachother to raise or lower the guide plate, two adjustments of the latterbeing indicated in full and dot-ted lines in Fig. 2. In all otherrespects, the apparatus is operated in the usual manner as describedinmyprior patent aforesaid, but the particular improvements hereinbeforedescribed insure a uniform rate of flow of unseparated liquor, whichmeans an increased rate of uniform separation, and at the same'timeeffects a more uniform distribution of the mud throughout the entireheight of the separating chamber and the total avoidance of the tendencyofthe mud to pack'in the lower portion of the latter and therebyobstruct the flow ofthe material from the accelerating chamber into theseparating chamber.

What 1 claim is:

1. A centrifugal separator comprising a rotatable bowl having acylindrical wall merged into the bottom by an inwardly inclined surface,an annular guide plate defining an antechamber adjacent said inclinedsurface, and means for adjusting said guide plate vertically to vary thespace between the periphery 0f the same and said inclined surface.

2. A centrifugal separator comprising a rotatable bowl having acylindrical wall merged into the bottom by an inwardly inclined surface,an annular guide plate deiining an antechamber adjacent said inclinedsurface, and a vertically adjustable foraminous support for said guideplate, whereby the space between the periphery of said plate and theinclined surface may be varied.

A centrifugal separator comprising a rotatable bowl having a cylindricalwall merged into the bottom by an inwardly inclined surface, an annularguide plate defining an antechamber adjacent said inclined surface,telescoping annular screens supporting the annular plate, and means forrelatively adjusting the annular screens to Vary the elevation of theannular plate and the space between the periphery of said plate and saidinclined surface.

4. A centrifugal separator comprising a rotatable bowl having acylindrical wall merged into the bottom by an inwardly in clinedsurface, an annular guide plate defining an antechamber adjacent saidinclined surface, telescoping annular screens supporting the annularplate, and bolts for securing the annular screens in dill'erent relativerertical adjustments to vary the elevation of the annular plate and thespace between the periphery of said plate and `said inclined surface.

In testimony whereof 1 allix my signature. i
